This paper will combine field results from two heavy and high viscosity crudes - one in Venezuela and the other in California. Electric Downhole Heating (EDH) systems were used to lower the viscosity of oil in the reservoirs to increase the flow rates of crude and improve the oil recovery. EDH systems are very efficient, reliable, and easily controlled solution to allow production of heavy, high viscosity oils. The total system is very space efficient both downhole and on the surface.
